Performance Evaluation of Full-Duplex IAB Multi-Cell and Multi-User Network for FR2 Band

One of the approaches to support high data rates in beyond 5G cellular networks is dense deployment small cell millimeter-wave (frequency range 2 (FR2)) ( $>24.5$ GHz) base stations. However, this stations leads cost, because it requires fiber backhaul connection with core network. prominent solution integrated access and (IAB) network proposed 3GPP Release 16, where some portion wireless spectrum used for serve instead fiber, remaining user equipment communication. The partition into degrades spectral efficiency IAB Thus, paper, we propose a full duplex (FD) enabled large-scale array systems enhance In FD network, node which transmits receives at same frequency/time resources. We consider multi-cell multi-user all interferences due transmission evaluate performance terms bit-error-rate efficiency. Moreover, an algorithm choosing different users based on cross-correlation RF precoder weights. Further, identification optimal beam’s index also synchronization signal block half-frame bit physical broadcast channel payload NR. Finally, successive interference cancellation self-interference mitigation digital domain.
